Effects of Minimal Exercise and Cognitive Behavior Modification on Adherence,Emotion Change,Self-Image,and Physical Change in Obese Women

The present investigation tested a 12-wk. treatment protocol which employed low intensity cardiovascular and resistance exercise as well as cognitive-behavior modification on 13 obese, previously sedentary women. Separate analyses were conducted on program maintenance, emotional change, and physiological change. Although self-motivation was lower in the treatment group than in the control group (n = 35), measures of exercise maintenance were significantly higher. Analyses within the treatment group only indicated significant improvements in measures of State Anxiety, Depression, Anger, Fatigue, Tension, and Vigor, also Health Evaluation, Body Area Satisfaction, and heightened Overweight Preoccupation, over the 12 weeks. Their feelings alter individual bouts of exercise indicated significantly increased Positive Engagement, Revitalization, and Tranquility, and reduced Physical Exhaustion. Maximum volume of oxygen uptake (VO₂max) significantly increased (2nd to 10th percentile), but not resting heart rate. No significant correlation was found between cardiorespiratory change and change in scores on depression and anxiety. No significant association was found between physiological change and change in body image Preliminary evaluation of the minimal exercise treatment was given. The need to replicate findings with larger and different samples was emphasized.
